Influence of model uncertainty and long term deformations in action effects calculation in reinforced concrete structures
Most codes of practice adopt a semi probabilistic design approach for the dimensioning and assessment of structures. Accordingly, structural safety is ensured by performing limit state verifications using design values determined with adequately calibrated ...
EPFL2024Shear and steel-fibre reinforcement for the punching resistance of flat slabs at internal and edge columns
Reinforced concrete flat slabs consist of a continuous, thin concrete plate that rests on a grid of columns. The supporting surface of the columns is very small compared to the floor plan dimensions, leading to concentrations of shear forces near the colum ...
EPFL2024Reuse of cut concrete slabs in new buildings for circular ultra-low-carbon floor designs
Corentin Jean Dominique Fivet, Célia Marine Küpfer, Numa Joy Bertola
The study explores an original idea that responds to the urgent need to reduce the detrimental environmental impacts of load-bearing floor construction in new buildings by reusing saw-cut reinforced concrete (RC) pieces salvaged from soon-to-be demolished ...
2024Mesh-based topology, shape and sizing optimization of ribbed plates
In this paper, we present a new parameterization and optimization procedure for minimizing the weight of ribbed plates. The primary goal is to reduce embodied CO2 in concrete floors as part of the effort to diminish the carbon footprint of the construction ...
Springer2024Model uncertainties in action effects and load bearing capacity calculation in statically indeterminate reinforced concrete structures
Aurelio Muttoni, Alain Nussbaumer, Xhemsi Malja
For the dimensioning and assessment of structures, it is common practice to compare action effects with sectional resistances. Extensive studies have been performed to quantify the model uncertainty on the resistance side. However, for statically indetermi ...
Ernst & Sohn2024Estimation of the bar stress based on crack width measurements in reinforced concrete structures
Estimating the stress of reinforcing bars and its variations in service conditions can be useful to determine the reserve capacity of structures or to assess the risk of fatigue in the reinforcement. This paper investigates the use crack width measurements ...
Ernst & Sohn2024Rising from rubble - Leveraging existing construction tools for upcycling concrete waste into slender walls
Katrin Beyer, Corentin Jean Dominique Fivet, Stefana Parascho, Qianqing Wang, Maxence Grangeot
In this paper, we present a new method for upcycling concrete rubble waste into slender walls through the lightweight digital augmentation of mainstream construction machines. By using such method, the environmental impact of concrete construction and demo ...
Springer2024The time-domain Cartesian multipole expansion of electromagnetic fields
Marcos Rubinstein, Farhad Rachidi-Haeri, Elias Per Joachim Le Boudec, Chaouki Kasmi, Nicolas Mora Parra, Emanuela Radici
Time-domain solutions of Maxwell’s equations in homogeneous and isotropic media are paramount to studying transient or broadband phenomena. However, analytical solutions are generally unavailable for practical applications, while numerical solutions are co ...
2024Engineering novel protein interactions with therapeutic potential using deep learning-guided surface design
Proteins are foundational biomolecules of life playing a crucial role in a myriad of biological processes. Their function often requires interplay with other biomolecules, including proteins themselves. Protein-protein interactions (PPIs) are essential for ...
EPFL2024Contradict mechanism of long-term magnesium and sodium sulfate attacks of nano silica-modified cement mortars - Experimental and thermodynamic modeling
The mechanisms of external sulfate attack on cement mortars containing nano silica have been studied under full immersion conditions after 3 years. The sulfate degradation processes were compared between sodium sulfate and magnesium sulfate solutions with ...
